Embodiment Construction

[0023] attached figure 1 Components of a mobile radio communication system, such as a digital cellular telecommunication system, according to an embodiment of the invention are shown. Specifically, attach figure 1 2 types of networks are shown, namely partly fixed networks (such as the public switched telephone network PSTN, such as the national telephone network, the integrated services digital network ISDN or the packet-switched public data network PSPDN) and public land mobile networks PLMN (such as UMTS mobile radio communication system). To link these networks, a Gateway GPRS Support Node GGSN is provided for determining the specific location of a mobile station MS in the digital cellular telecommunication system and for routing incoming calls towards this mobile station MS.

[0024] To this end, the GGSN is connected to a functional unit called the Home Location Register HLR, in which two types of information are stored, subscriber information and mobile information, t...

Abstract

There may be gaps in the base station's reordering buffer due to packet loss due to misinterpretation of a NACK as an ACK in the base station. According to the invention, after the receiver has sent a negative acknowledgment message (NACK) for the second data packet, when the receiver has decoded the first data packet without error (possibly after several retransmissions), the receiver sends The transmitter sends a Revert (REV) message, wherein the first data packet is sent along with an indicator that the first data packet is a new data packet. The REV message informs the base station that the first data packet was decoded without errors, and that the second data packet is still missing at the receiver, so that the base station can resend the second data packet.

Description

technical field [0001] The invention relates to the field of packet switching data transmission, especially the packet switching data transmission in radio mobile communication systems. More specifically, the present invention relates to a method for transmitting data packets from a transmitter to a receiver, a system for transmitting data packets from a transmitter to a receiver, a base station for a mobile radio communication system, a system for For a mobile subscriber station of a mobile radio communication system, a computer program for controlling the transmission of data packets from a transmitter to a receiver of a mobile radio communication system.
